The commonest laser-active unusual earth ions and host media along with some typical emission wavelengths are shown in the following table:
These ions enable the crystal to amplify light at the laser wavelength by way of stimulated emission, when Strength is provided for the crystal by way of absorption of pump light (�?optical pumping
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and also the upper-condition life time.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
A high floor high quality is of course critical. Specifications of floor flatness are frequently much better than . This aids to avoid equally scattering losses and wavefront distortions which can degrade the laser's beam good quality. Additionally, scratch and dig specifications
The utmost probable doping focus can count strongly on the host materials and its fabrication strategy.
The host crystal is considerably more than simply a way to repair the laser-Energetic ions at certain positions in Place. Numerous Houses from the host content are important:
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
Individuals surfaces that happen to be handed by the laser beam are Ordinarily either oriented at Brewster's angle or have an anti-reflection coating.
Distinctive crystalline supplies are quite diverse regarding their hardness and other Homes, which determine with which techniques And just how effortlessly they may be Slash and polished with top quality.
The medium ought to have a higher transparency (low get more info absorption and scattering) while in the wavelength locations of pump and laser radiation, and superior optical homogeneity. To some extent, this depends upon the standard of the fabric, based on details on the fabrication procedure.
With that concept, 1 would not need an additional saturable absorber crystal, to ensure a person could make far more compact Q-switched laser setups with reduce inside parasitic losses. On the other hand, unwanted Uncomfortable side effects might also manifest, for instance getting undesirable valence states on the included ions or Electrical power transfers.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
